Abstract/Executive Summary
Oral cancer remains a significant global health concern, with late-stage diagnosis contributing to poor survival rates. Multispectral imaging (MSI) has emerged as a transformative tool in early detection, offering non-invasive, real-time visualization of mucosal abnormalities. This article examines the clinical applications, technological mechanisms, and research-backed advantages of MSI in oral cancer screening. Case studies demonstrate its efficacy in identifying premalignant lesions, while comparisons with traditional methods highlight its superior diagnostic accuracy. Additionally, we review leading MSI devices, discuss limitations, and explore future innovations. Dental professionals and oncologists will gain actionable insights into integrating MSI into routine practice for improved patient outcomes.
1. Introduction & Background
Oral cancer accounts for over 350,000 new cases annually worldwide, with a five-year survival rate below 50% when diagnosed late. Early detection is critical, yet conventional visual and tactile examinations often miss subtle precancerous changes. Multispectral imaging, a non-invasive optical technique, enhances early diagnosis by capturing tissue reflectance at multiple wavelengths, revealing biochemical and structural abnormalities invisible to the naked eye.
This article explores MSI’s role in digital dentistry, its clinical adoption, and how it addresses current diagnostic challenges.
2. Main Body Sections
A. Clinical/Technical Overview
- How MSI Works:
- Uses LED or laser light at specific wavelengths (400–1000 nm) to assess tissue oxygenation, vascularity, and keratinization.
- Advanced algorithms analyze spectral signatures to differentiate malignant from benign lesions.
- Evolution of MSI:
- Originally developed for satellite imaging, now adapted for medical diagnostics.
- Combines autofluorescence and reflectance imaging for higher specificity.
B. Case Studies & Clinical Applications
- Case Study 1:
- A 58-year-old smoker with a leukoplakic patch. MSI identified high-risk vascular patterns, confirmed via biopsy as dysplasia.
- Case Study 2:
- MSI-guided biopsy in a patient with oral lichen planus reduced unnecessary biopsies by 30%.
